Error with including mbed objects into class

Hi i wrote a class and wanted to add a BusOut object. But when I try to compile the program there are some errors occuring:

Error: No default constructor exists for class "mbed::BusOut" in "main.cpp", Line: 17, Col: 18 Error: No default constructor exists for class "mbed::BusOut" in "main.cpp", Line: 17, Col: 18

Heres my class:

class display{ private: int width; int height; public: display(); BusOut coloumns; BusOut rows; };

display::display(){ this->width = 5; this->height = 7; }

I want to assign some portpins to the bus in the display::display constructor. I know that the portpins are currently missing but the error has to be solved first. What do I have to do to include mbed objects into classes?

all the best and thank you for your attention
